I'm considering getting an M2C for my 120mm refractor for grab & go sessions during winter, when setting up a GEM would be too much. I wonder how it performs (eg how smooth are the movements or anything else worthy of mention) with temperatures of, say, -15C (5F).

 

Any experiences would be appreciated.

 

Thanks,

Razvan

All I know is that I don't operate well at 5F.

I have never gone that cold: it just doesn't happen here! However, I have never noticed any problem with an M2 mount at any other temperatures (ranging from ~32F to 110F (not night-time!)). Basically it is just teflon on metal, and you adjust the tension as required; so I don't see how the temperature would affect anything apart from a possible tension adjustment.

 

All the best,

 

Dean

Agree with Dean. I've never gone that cold either but there's no grease or intricate mechanics.

Thanks to both. So it becomes a matter of whether teflon behaves differently in cold weather. Something I need to research.

You should have no issues at all down to 5F or even 0F... probably lower still, but we've never actually put it to the extremes for testing as it will probably work in much colder temperatures than a person can. We talked about this among some of the staff here too, and nobody can remember anyone having reported issues with their M2C or even the older M2 model due to cold. The only exceptions to this were a handful of cases where people applied some kind of grease to the Teflon bearings (...please don't do that), but as long as the bearings are clean and dry like we ship them you should be able to work in some seriously uncomfortable temperatures. Hope that helps! Should be a great match for your refractor.
